Claims

[Scope of utility model registration request]

A refrigeration cycle formed by a compressor, a condenser, a throttle device, and an evaporator is activated when the load on the evaporator decreases, and the pressure is branched off from the high-pressure side discharge pipe of the pressure machine to supply refrigerant to the suction pipe of the compressor. A first circuit, a second circuit that branches off from the high-pressure side liquid pipe of the compressor to supply refrigerant to the suction pipe line and constitutes a low load compensator together with the first circuit; Provided in the liquid receiver, after reducing the pressure of the refrigerant in the high pressure side liquid pipe in the second circuit, heat exchange is performed so as to subcool the refrigerant in the liquid pool in the condenser or liquid receiver. A refrigeration system comprising a heat exchange path for supplying heat to the suction pipe.
